Summary and plans for current ECMWF operational systems
• Ocean model configurations
• Current ocean model is based on NEMO V3.4.1 with local ECMWF modifications
• Same ocean grid with about 0.25 degree resolution used for all operational systems
• Ocean analysis systems (BRT and RT):
• ocean5: NEMOVAR 3D-VAR FGAT
• T/S/SLA/SIC observations, SST via relaxation
• All forecasting systems are coupled (atmospheric resolution list below)
• HRES CY47R1 (30/6-2020) 9 km deterministic 10 days twice daily
• ENS CY47R1 18 km 51 members 15 days twice daily
• Monthly CY47R1 36 km 51 member 46 days Monday and Thursday 0z
• SEAS5 CY43R1 (November 2017) 36 km 7 months every month, 13 months every 3 months
• Plans for the next ocean model upgrade (2022 target)
• Upgrade to NEMO V4. Biggest change is the LIM2 (mono-cat) to SI3 (multi-cat) sea ice model
• Resolution will likely stay the around 0.25 degree for the ocean.

FOAM-UK overview of status and plans
New and upcoming operational system developments:
• Operational implementation of global 1/12° FOAM will go live in Dec 2020. Developed for UK Royal Navy.
• Coupled NWP development and implementation. Deterministic 10km resolution atmosphere/land, 1/4°
ocean/sea-ice, with weakly coupled DA. Coupled ensemble (with 1/4° ocean). Planned for operational
implementation in 2021.
• Development of a global ocean ensemble and hybrid ensemble/variational DA. Planned for operational
implementation in 2023 to improve the ocean component of coupled NWP ensemble system. (Long time-
scale partly due to new supercomputer system expected in 2021/22 and the associated porting work).
Assimilation of new data types:
• Assimilation of sea-ice thickness: daily along-track freeboard from Cryosat2 and thickness from SMOS.
• ESA A-TSCV project: testing impact of assimilating Total Surface Current Velocity (TSCV) from future missions
like SKIM (in collaboration with Mercator-Ocean).
• SWOT preparation: work started in 1.5 km shelf-seas configuration, global next year.
• Operational ocean colour assimilation in shelf-seas physical/biogeochemical model.

OPST-3, GoTo meeting – 7, 8 and 10 December 2020The Oceanographic Modeling and Observation Network (REMO)
is a research group formed by Federal Univ. of Bahia (UFBA), Federal Univ. of Rio de Janeiro (UFRJ), Petrobras Research
Center (CENPES) and the Brazilian Navy Hydrography Center (CHM), that holds the REMO-CHM ocean operational
forecasting system (OOFS) for the Atlantic. HYCOM 1/4o 1/12o 1/24o
• The OOFS uses HYCOM and the REMO Ocean Data Assimilation System (RODAS)
based on EnOI. HYCOM+RODAS assimilates Argo T/S data, UK MetOffice OSTIA
SST and along-track AVISO SLA data.
• Assimilation is performed twice a week, but 5-day forecasts are performed daily
forced by a combination of CHM-COSMOS atmospheric forecasts (3-d window) and
NOAA/NCEP/GFS forecasts (4 to 5-d window).
• A system with 3 nested grids is employed today
• A new OOFS - operational since March 2020 - will replace the current system in the
first semester of 2021.
HYCOM 1/12o 1/24o
• UFBA and UFRJ produced 4 10-yr reanalysis in 2019-2020 from 2008 to 2017.
• UFBA develped a preliminar version of an EnKF with 11 members only, and will
improve it to 30-members in 2021.
• Efforts on OSSEs with SWOT and on OSEs with SSS are underway.
